PE1-4.5 Debugging Techniques & Applications
You can test an Arduino board and diagnose IDE problems, apply systematic debugging techniques, and describe deployed applications across agriculture, medicine, security, home, automotive and consumer electronics.
Most embedded faults are hardware — a loose wire, a shared ground missing, a supply that sags when the motor starts — so the first debugging move is to check the physical layer, not the code. Build a habit of isolating: prove the board runs blink, then prove the sensor reads, then combine. The case studies are worth reading as project templates; the agricultural and home examples in particular are within reach of a student project with the parts from Unit 3.
Work through these
Testing the Arduino board
Checking the board itself before suspecting your code. A structured first check saves hours of debugging software that was never the problem.
Problems with the IDE and their fixes
The environment's own failure modes, which are numerous and mostly about ports and drivers. Having the list is worth more than understanding any one of them.
Systematic debugging techniques; isolating hardware from software faults
The method rather than the tools: halve the problem, and separate hardware from software before going deeper. It is the most transferable thing in this course.
Applications in agriculture
A worked application area, where the sensors are the ones from the interfacing topic. It shows what a complete small system looks like.
Applications in medical and security systems
Two application areas where getting it wrong matters more. Worth reading for the reliability requirements as much as the circuits.
Applications in home appliances
The domestic applications, which is where most of these projects actually end up. Power consumption becomes the design constraint here.
Applications in automotive systems and consumer electronics
Two more areas, closing the course. The automotive one is a useful contrast because the environment is far harsher than anything above.
